Great idea. I was a business consultant for a decade, so helped a lot of corporate marketing departments and sole proprietors with marketing. I actually have a decent Twitter presence under my own name, so I would probably just use that to retweet Hive content and otherwise participate. I could definitely help be a part of a cohesive marketing plan.

I also create training materials and have been supported 100% by online courses the last few years. I think weaving the marketing and training together is key. As much as possible, each welcome should include a spot of training. The "How" is what stops a lot of people, even after you inspire them.
